FASTENER FOR WINDOW AND DOOR SCREENS.

Specification of Letters Patent.

Patented Mar. 31, 1914:.

Application filed December 15, 1910'. Serial No. 597,443.

To all whom it may concern Be it known that I, FRANCIS M. KING, acitizen of the United States, residing in the city and county ofPhiladelphia, State of Pennsylvania, have invented a new and usefulFastener for Window and Door Screens, of which the following is aspecification.

My invention relates to a screen for a window, door, or the like, andconsists of novel means for fastening such screen to the frame therefor,as will be hereinafter described and definitely claimed.

For the purpose of explaining my invention, the accompanying drawingillustrates a satisfactory reduction of the same to practice, but theimportant instrumentalities thereof may be varied, and so it is to beunderstood that the invention is not limited to the specific arrangementand organization shown and described.

Figure 1 represents a perspective view of a screen-fastener embodying myinvention. Fig. 2 represents a perspective view of a detached portion onan enlarged scale, Fig. 3 represents a longitudinal section on line a:-wFig. 1, on an enlarged scale.

Similar letters of reference indicate corresponding parts in thefigures.

Referrlng to the draw1ngs:-A designates an insect screen, which 1scomposed of a piece of suitable fabric such as gauze or netting, thesame having connected with it at the border portions thereof atintervals the gromets or eyelets B.

C designates buttons which have pins D passed eccentricallytherethrough, the same being adapted to be driven into the frame E towhich the screen is applied, thus retaining said buttons in position.The buttons are formed each of a body F and head G of rubber or otherelastic or pliable material, said body being substantially ofcylindrical form and the head flaring or increasing in width from saidbody so as to overhang the latter and consequently the gromet or eyeletwhich said body subsequently occupies.

It will be seen that the buttons are applied to the frame E at places tobe occupied by the gromets B, allowance being made for stretching thescreen, the gromets being drawn over the buttons and sprung over theoverhanging ends or heads G into position on the bodies F, said headsyieldin so that the gromets may pass over and a under or behind thesame, it being evldent that said latter prevent the gromets from risingon the buttons and consequently disengagement and loosening of thescreen. Should the screen be subjected to drafts of air its strain thenis directly on the side of said bodies F which are yielding so as to beeasy on the screen, preventing the same, under ordinary circumstances,from being rent about the gromets.

Under ordinary circumstances, the buttons, when set or adjusted on theframe are fixtures thereof, and so need not be disturbed, but shouldthey wear on the sides of the bodies, where the gromets contacttherewith, the buttons may be turned so that their bodies present agreater diameter or swell of the same to the contact of the gromets andthus hold the screen taut, it being evident that when the screen is tobe removed the gromets are forcibly moved over the heads G, and sosprung or stripped therefrom, the heads sufiiciently yielding to permitthe same.

In order to set the buttons primarily on the frame so that theeccentrically-disposed pins or axes thereof occupy the right position, Iplace on the top of each button an indicator H, which in the presentcase, is of the form of an arrow or index finger and cast on the buttonwithin the circumference of the head G, the indicators on the sidespointing inwardly, those on the top pointing downwardly, and those onthe bottom pointing upwardly showing where the axis or pins D are to belocated on the frame and driven into the latter, and so the severalgromets around the screen may be sprung over the buttons and the latterretain their hold on the former in the taut or stretched condition ofthe screen.

In order to assist in removing or stripping the gromets from thebuttons, there is attached to the piece of screen material the tab Jwhich forms a finger piece for evident purposes, and provides means formarking the screen with the name or location of the window, door, etc,that it occupies preparatory to storage so that when a screen is to bereapplied, it may be presented to the proper window, door, etc, wherethe previous adjustment of the buttons remains.

The gromets form a lining for reinforcing the openings in the piece ofmaterial that they occupy, and the diameters of their openings aregreater than the diameters of the bodies of the buttons, so that thegromets have play on the buttons both in applying and removing the sameto and from the latter, as most apparent in Fig. 2.

Having thus described my invention What I claim as new and desire tosecure by Letters Patent is 4 1, In a screen fastener of the characterdescribed, a rotatable button formed of a cylindrical body of pliablematerial and a head of greater diameter than said body,
